Application tiled September 21, 1909. Serial No.l 518,847.l f'
ments in Electric-Lain Sockets, 'of which the following is -a speci tion.
The object of my invention is to provide an electric incandescent lamp socket with a simple switch mechanism glving a double break when the key turned to cutout the l current. y
In the accompanying drawing, Fi a vertical section, of my improve re 1 is socket,
the lined inclosing shell being indicated iny dotted lines; Fig. 2 is a similar view with the ition; Fig. 3 is a plan-view of the socket Fig. 2, with the upper insulating button removed; and Fig. 4 is a sectional view on the line 4 4, Fig. '3.
My resent improvement is especiall applicab e tothat type of socket in `Whic t e insulating body 1s in two parts juxtaposed.
and inclosing the switch mechanism. A and B are the two parts or buttons having in the adjacent faces recesses to form chambers one .to receive the switch mechanism. The two parts.' A and B may be secured together in the usual manner b the two terminal posts D, D', andon the ower face of the lower-button are mounted the lamp-receiving terminal screw shell S and center contact C. The screw shell S may be electrically connected to the terminal post D1 in any suitable way, while the spring contact C is electrically connected to the post D through the switch mechanism. This mechanism includes a horizontal rotar 'spindle f with handle or key F and mounte in slots in the U-shaped frame E, which may be secured by a screw e (Figs. 1 and 2) to the button A. On the key spindle f is mounted with the usual lost motion a cam iece or tumbler G and against the undersi e of this is pressed the moving contact piece J by a spiral sprmg lc. This contact iece J is guided vertically by the upright ame E, the two legs of which "pass through slots in said piece J.
Connected to or forming part of the post D is a contact arm d with which the cam G of the switch makes connection when the cam ils indits vertical position,'as shown in Figs.
' In the lower part of the chamber` which contains the above'described switchmech.- anism is a spring contact finger H, which is electrically connected [tothe center contact C for the lamp (Fig. 4). When the cam G is turned to the upright position and one end makes contact with the arm d, the other i end presses down the contact` iece J to makeA connection with the iinger and thus the circuit will be closed through the lamp, Figs.
1 and 4,-but when the switchkey is given a4 quarter turn, not only' will .the contact be broken between the cam G and arm d, but
the spring'lc will ress the piece J out of contact-.with the ger H, and so givea double break.
I claim as my invention:
1. An electric lamp socket, having an insulating body, lamp-receiving terminals, and a doub ebreak swltch mechanism compris' ing a contact, connected to one o said ter- `m1na1s, a spring-actuated contact piece. to
make connection therewith, a key spindle with a cam to act on thecontact pleee, a
hso
e-break switch mechanism, compris- 4 cam, va movable contact piece guided on the y frame to make electrical connection with the'` said contact, a spring to vpressthe contact piece to the cam, a pair of binding posts and a contact armY for the cam connected to one of 'the binding posts. t Y In testimonygwhereof I 'havesigned my name to this specification, in the presence of two subscribin' witnesses.
